openstack-ardana: fix workspace cleanup

The openstack-ardana-heat cleanup job is triggered, even after a
successful job, to suspend the heat stack used by the main
openstack-ardana job. The cleanup job needs access to the
workspace used by the main job, to pass parameters via
a properties file, so the workspace used by the main job
mustn't be deleted in case of success.
